The MSP Multisample file, it's not a good file to create a New Drums.set because, the MSP file, does not support Stereo Wav files samples, but only Mono Wav files samples....A Drums set need Stereo and not Mono drum samples (wav/aiff)...For Ketron, Stereo wav samples support only the INS file, however as users we can not create INS file... INS file can to create only the Ketron Factory, and some collaborators of Ketron....However we,as users,can not create MSP Drums (like Turkish version), without update about this...And of course,it's unacceptable,for a keyboards with 4000 euros cost....
